Led Driver with an adjustable current level by I2C

S. Gaudreau

Hi,

Do you have a list of LED Drivers with the following features:

- I2C interface.

- 25-50mA current max per output.

- Dimming possible by current adjustement by I2C, Not by PWM

I'm having a hard time with the selection guides. Event if I select I2C, often, it's an internal PWM that does the dimming.

Thanks !

OK,

It's a short range camera system. That is why we don't want any adjustment with a PWM.

Thanks

i think LP5008 may be suit for your system, it has internal analog dimming mode without pwm pulse.
